IMPROVEMENT IN MINCE AND SAUSAGE MEAT CHOPPERS.

Specification forming part of Letters Patent No. 222,079, dated November25, 1879; application filed August 11, 1879.

To all whom it may concern Be it known that I, J oniv IRVEN ROUGH, ofBuchanan, in the county of Berrien and State of Michigan, have inventedcertain new and useful Improvements in Mince and Sausage Meat Choppers;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification,and in which- Figure 1 is. a side elevation. Fig. 2 is a bottom view;Fig. 3 is a plan or top view, and Fig. 4 is a vertical section.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to machines for chopping or mincing meat forsausages; and it consists in the combination, with an intermittin gly-rotating cylindrical chopping-block and a pitman reciprocatingvertically through its center, of a pair of cutters or chopping-knivesaffixed upon said pitman, and so constructed and arranged that inoperating the machine they will gradually work the mincc'meat toward thecenter, while at the same time the cutters, though operatedsimultaneously, will strike the meat at different points or places as itpasses under them, substantially as hereinafter more fully set forth.

In the drawings, A A is' the frame, upon the top of which rests anannular plate, a, supporting the intermittingly-rotating chopping-blockB, which consists of a hard-wood cylinder hav'ing a central perforation,1), surrounded by a tubular guard or sleeve, 0, which is attached by anannular flange to its upper side or face. Upon the under side of thecylinder B is secured a concentric ratchet-wheel, G, which engages witha spring-catch or dog, cl, and pawl e, pivoted in the upper arm of abell-crank, E, to the lower or horizontal arm of which is hinged apitman, D, the lower end of which is coupled upon a crank-shaft, F. Thusby rotating shaft F an intermittinglyrotating motion is imparted to thecircular chopping-block B by the pawl e, bell-crank E, and pitman D.

a central pivot. Pitman H is hinged at itslower end to a link, H,pivoted upon the crank-shaft F, and passes tl lrough a slottedcross-bar, A, which forms a guide for the vertically-reciprocatin gpitman H.

The cylindrical chopping-block Bis provided with a raised guard orannular flange, h, which rotates with it and forms, with the flat top orface of the block, a receptacle for the meat to be minced or chopped up.The shaft F is provided with a fly-wheel, I, and suitable gearing,

K, for operating it.

It will be observed that the cutters or chopping-knives G G are securedupon opposite sides of the head of the pitman H, so as to leave a narrowspace bet-ween them, and that they diverge from each other from thecenter toward the periphery of the chopping-block.

By this construction and arrangement of the cutters the mince-meat is,as the block rotates,

gradually drawn from the outer edge toward the"center, regardless ofwhat way the block rotates; and, again, the ends of the cutters G G,flaring from each other, prevent these from striking the mince-meattwice in the same place, as they would be apt to do if they wereparallel to each other their entire length; hence, the meat is choppedup thoroughly and evenly, and in less time than with choppingmachinesnot provided with my improvement.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- As an improvement" in mincing andmeatchopping machines, the combination, with an intermittingly-rotatingcylindrical choppingblock and a pitman reciprocating vertically throughits center, and mechanism for operating said block and pitman, of a pairof cutters or chopping-knives, G G, secured upon In testimony that Iclaim the foregoing as opposite sides of the pitman-head, but divergmyown I have hereunto affixed my signature ing or flaring gradually fromeach other from in presence of two Witnesses.
